The finer points of coil handling for fineblanking: Selecting equipment to produce flat, straight stripFineblanking operations require a heavy-duty press and special tooling. To produce straight, flat strip for the press and feed, stampers need a coil cradle, coil end peeler, debender, and hold-down arm, straightener, loop control.

Is metal roofing fabrication right for your shop?: How to ensure your roll forming operation is a good fitWhen deciding wheher or not to produce roofing panels, you need to determine your ROI, based on if you can use existing equipment or need new equipment, the required panel appearance; possible line configuration; and material handling options.

Straight to the point: The importance of straighteners in stamping operationsThe straightener, when set properly, removes the coil set, or curvature of the rolled material. If the machine is used or set incorrectly, the coil set can remain in the material, even after being struck in presses with capacities to hundreds of tons. This can cause a variety of problems: out-of-tolerance parts, difficult feed operations that can disrupt and slow performance, and, to some extent, additional wear and tear on feed line components and tooling.

Maintaining a slitting line: Tips for extending equipment lifeA slitting line can operate efficiently for 20 or more years if properly maintained. Modern slitting lines are high-performance machines that are intended to produce 24 hours a day, 365 days a year. As a result, stampers must be sure that all line elements are properly maintained, which represents a titanic effort if you don't understand what components are critical.

How to avoid slit-in coil slitting problems: Controlling variables prevents edge wave, width inconsistencies, burrsProblems that can arise during metal slitting include poor edge quality, edge burr, edge wave, camber, crossbow, knife marks, and slit width that is out of specification. Some slitting problems can be attributed to poor metal quality; however, it is much more common for the problems to be caused by other variables and factors during the slitting process.

Feed to registration: A different way to process round, nested parts efficientlyFor applications such as clutch disks, oil seals, oil filters, and other round stampings, feed to registration with scroll-slit material can reduce scrap rates and, in some cases eliminate the need to retool the job.

Doing its level best: Automotive blanker's leveler eliminates costly shape defectsA precision roller leveler, installed between the coil payoff reel and the press equipment, allows an operator to stretch the edges when necessary to compensate for loose centers or stretch the center to compensate for loose edges before the blanking operation.

The big payoff: Pallet uncoilers help to reduce scrap, labor, and safety costsTraditional coil slinging and hoisting for vertical dereelers and positioning them in coil cradles requires extra personnel and is time consuming because production must be stopped. When a line isn't running—it's not making any money. To keep your line moving, consider a pallet uncoiler.

Technological quantum leap: Multiblanking line improves output, creates new opportunitiesArme S.A., a Colombian service center, was producing cut blanks for several local, small customers using a 48-year-old Stamco cut-to-length line purchased more than 20 years ago. It served them well over the years, but the company realized it needed to upgrade its technology to take advantage of the market opportunities it saw growing around them.

Leveling flat-rolled strip: How roller levelers handle the taskOperating a leveler requires training and skill, but computers are making the task much easier. A computer can quickly set the machine to a good starting point and allow very fine adjustment of the back-ups. Once the leveler is delivering good results on a particular coil, the settings can be saved and called up later. That saves setup time when coils are partially run and then sent back to stock.

For flawless cosmetic finish, start at the head: A clean straightening head prevents debris damage during coil feedingStamping cosmetic parts in coil feed lines can be challenging. Cleaning the coil feeding head properly can eliminate waste or scrapped parts caused by debris and contamination.

Choosing between feeding your new stamping line coil or blanks?: Maybe you should feed it bothStampers today need to process more grades and types of material than ever before, yet are under relentless pressure to reduce costs. They increasingly rely on systems integrators and equipment suppliers to design and install versatile stamping lines with quick-change capabilities. A notable case was that of a truck frame and chassis components manufacturer. It worked with vendors to develop a line that processes material up to 0.280 in. thick and 72 in. wide, in a range of yield strengths, in three forms – coil, blanks, or sheet.

Coil feed line considerations when stamping HSS: Making adjustments for stronger steelWith its higher tensile and yield strengths, HSS is stronger at any given gauge than conventional "mild" steels. Initially, lighter-gauge HSS was used to replace heavier-gauge mild steel to reduce weight in many automotive parts, and this continues to be the most widely used application for HSS. However, as a new trend to run thicker and thicker gauges of HSS continues, stamping fabricators are evaluating their press feeding and coil handling equipment, as well as press tonnage capacities and die designs to ensure that these harder parts can be formed effectively. The dynamics of HSS have a bearing on feeding, straightening, and coil handling equipment.

Understanding press feeds: A primer for the ‘nontechie’Major technology shifts in how stamping presses are fed have allowed press feed technology to evolve, enabling stampers to realize increased processing speeds, improved processing flexibility, easier setup, and better quality and reliability. Even with today's advancements, a press feed must meet three basic and important criteria to be successful: Setup must be flexible. It must deliver the material with sufficient precision into the tool and die. It must feed at the correct time. Advancements in feed technology include pilot release, space-saving line configurations, transfer/progressive operations, and scratch-free processing.
